Assuming that most people's GH comes in 10 iu vials, why is 4iu per day such a popular dose? Unless I'm really missing something, regardless of how much bac water you add, you would take 2 - 4iu doses and then on the third dose you would draw the remaining 2iu, then have to reconstitute another vial to draw the remaining 2iu to complete your dose. For those that do it this way, do you use the same slin pin to draw the 2iu out of 2 separate vials and use it to inject? Seems like asking for problems IMHO. Why not just take 3.33iu or bump to 5iu?
